What are the main levels of organization in the human body?

The body is organized from the simplest to most complex levels: chemical, cellular, tissue, organ, organ system, and organism.

Why is anatomical position important in anatomy?

It provides a universal frame of reference for describing the location and direction of body parts accurately.

What is homeostasis and why is it vital?

Homeostasis is the body’s process of maintaining internal stability, such as temperature and pH balance, which is necessary for normal function and survival.

What are the key elements that make up most of the human body?

The body is primarily composed of oxygen, carbon, hydrogen, and nitrogen.

What is the main difference between organic and inorganic molecules?

Organic molecules contain carbon and hydrogen, while inorganic molecules usually lack carbon.

What does the cell membrane do?

It acts as a selective barrier, controlling the movement of substances in and out of the cell.

Why are mitochondria called the “powerhouse” of the cell?

Because they produce ATP, the main form of energy that fuels cellular functions.

What are the four major tissue types in the human body?

Epithelial, connective, muscle, and nervous tissues.

How does the hierarchical organization of the human body facilitate specialized functions?

Each level of organization—from chemical to organism—allows increasing complexity, enabling cells to specialize, tissues to perform coordinated activities, and organs and systems to maintain homeostasis efficiently.

What are the major functions of the skin?

The skin protects the body, helps regulate temperature, provides sensory information, and prevents water loss.

Why are oxygen, carbon, hydrogen, and nitrogen considered essential for life?

These elements form the backbone of macromolecules such as proteins, carbohydrates, lipids, and nucleic acids, which are critical for energy, structure, and information storage.

How do ligaments and tendons contribute differently to musculoskeletal mechanics?

Ligaments stabilize joints by connecting bones, limiting excessive movement, while tendons transmit muscle-generated force to bones, facilitating precise and controlled motion.
